In our experiences of 22 congenital bile duct dilatations (CBD), 3 cases were accompanied by chronic calculous pancreatitis. Through the management of those 3 cases, we obtained following suggestions. 1) Some of 'pancreatic calculi of unknown etiology' (which are more often found in female than in male) may be associated with anomalous arrangements of the pancraticobiliary ducts. 2) Pancreatolithiasis in chole doc ho-pancreatic common channel anomalies and alcohol abuse may differ in pathogenesis and composition of the stone. 3) An appropriate drainage procedure for the pancreatic duct system should be included in the treatment of CBD with pancreatolifhasis.
